I should have seen if it was okay to take Excedrin extra strength during breastfeeding before taking it, but I didn't. How long should I wait after taking before I can feed again? I only took one tablet.

Since they put excedrin extra strength back on the shelves it came in a white bottle with an EX on the pill itself, today i bought a bottle and the bottle is back to the clear green and the pill is back to having just an E on it, has anyone noticed this? I wish they'd just stick to one thing ...
